METHOD AND APPARATUS FOR ENCODING VIDEO AND METHOD AND APPARATUS FOR DECODING VIDEO DETERMINING INTER-PREDICTION REFERENCE PICTURE LIST DEPENDING ON BLOCK SIZE

摘要

Provided are a method of determining a reference image for inter-prediction and an inter-prediction method according to the method of determining a reference image for inter-prediction. The inter-prediction method includes: determining, when a current slice is a B slice, a reference picture list used by a current prediction unit from among prediction units included in a coding unit; and outputting, when a size of the current prediction unit is 4X8 or 8X4, inter-prediction index information of the current prediction unit indicating a reference picture list from among a LO list and a Ll list, and when a size of the current prediction unit is not 4X8 or 8X4, the inter-prediction index information of the current prediction unit indicating a reference picture list from among a LO list, a L-1 list, and a bi-prediction list.
